Haefely Test AG products

Cable test termination systems are used for high voltage testing of power cables. Before high voltage (AC or Impulse) can be applied the power cable need to be prepared and terminated in a special way order to control the electrical field distribution along the ends.

The DEC 5 is used for decoupling auxiliary equipment from an EUT tested with either 1,2/50us - 8/20us combination wave impulses or 10/700us impulses up to 6.6kV peak. It is used to decouple unshielded symmetrical data and signal lines according standards IEC  61000-4-5 Edition 1 and 2 and ITU  K.44. Up to 4 wires can be tested simultaneously. To obtain maximum flexibility only decoupling and protection elements are included in the DEC 5. Coupling circuits, which depends on the EUT to be tested, can be placed separately in the test setup. Manual coupling selection of the protection elements for best protection of the auxiliary equipment. Default protection elements are gas arrestors and breakdown avalanche diodes. With such elements the capacitive load to the EUT lines is small. The decoupling elements can be selected easily. It is also possible to test without any protection elements.

The DEC 6 is used for decoupling auxiliary equipment from an EUT tested with 10/700us impulses up to 6.6kV peak. It is used to decouple unshielded symmetrical data and signal lines according standard ITU K.44. Up to 4 wires can be tested simultaneously. To obtain maximum flexibility only decoupling and protection elements are included in the DEC 6. Coupling circuits, which depends on the EUT to be tested, can be placed separately in the test setup. Manual coupling selection of the protection elements for best protection of the auxiliary equipment. Default protection elements are gas arrestors and breakdown avalanche diodes (ABDs). With such elements the capacitive load to the EUT lines is small. The decoupling elements can be selected easily. It is also possible to test without any protection elements.
